To all witom it may concern:

Be it known that I, EMMIT G.Lla'rra, a

i "citizen of the United States, residing at Syracuse, in the vcounty ofOnondaga and State of New York, have invented a new and useful Imrovement in Type-Writing p Machines,"of w ich the following is aspecication.

\ `This invention relates to improvements in typewritlng machines andmore particularly n to mechanisms employed in front strike or,

f paper platen to y ao visible writing ty ewriters for enabling ythe eshifted to place 1t in printing relation with one or another of thedifferent sets of type on the type bars, and to other associated arts ofthe machine.

The objects o` the invention are to produce a shifting support for theplaten carria of front strike or visible writing typewriters thatenables the carriage to be made 'lighter than is usual in machineshavinga shifting platen; that is free from slidmg `friction; that -iscomparatively inexpensive to manufacture and assemble in the machine andcan bev quickly dismounted; also to provide actuating connections forcertainparts mounted on the carriage and shifting support that permitsuch parts to be actuated from the keyboard equally, well when thecarriage is inone or another of its` dilerent printing positions; and tootherwise improve theshift mechanism and associated parts of t pewritingmachines in the respects hel-cina ter idescribed and set forth in theclaims.

Fig. 8 is a plan View on an enlarged Scale, partly in section, oftheribbtmI vibrating mechanism, showing the parts `im the same positionas in Fig. 1.

A" represents the Lstationaryi or main frame; B the paper platen, and Cone of the series of pivoted type bars of the machine. These parts maybeof any suitable construction, but are preferably'constructed andarranged as in the Moyertypewriter, which is disclosed in variouspatents and pending ap: plications in the name ofHarvey A. Moyer, OscarC. Kavle and Emmit G. Latta.

As shown the main frame 'is provided with a top plate a which isdetachably secured in place by screws, or other fastenings. rlhe 'platenB, as usual, is journaled onA a carriage arranged to travel horizontallycrosswise of the machine. The complete carriage is not shown, as it isnot essential to an understanding of this invention. It consists of endpieces or frames connected by a base frame or bar b and a front or scalebar b. lb2 indicates the rack bar on the car-` riage which meshes with apinion bs connected to t-hecarriage escapement, indicated at b4, forcontrolling the letter space movements of the carriage in the usual Way.The type bars are pivotally mounted in an arc in any suitable way on anupright segment or support c which is fixed in thestationary frame, andare adapted to swing upwardly and rearwardly to make the impressions atthe front portlon of the platen. Each type bar is provided with aplurality of type, and the carriage is adapted to be shifted to placethe platen in printing relation with one or another of the sets of typeon the type bars.

` The platen carriage is 'supported and adapted totravel horizontall ona shift frame D which is adapted to shifted up and down for placing theplaten in position for printing with one or another of the dif- Theshift frame D shown consists of an open cradle-like casting ofrectangular form which has projections d d2 extending, respectively,forwardly and rearwardly `from the middle portion of the frame, and isprovided with opposed parallel hardened steell of the Moyer typewriterwithout change in any of the carriage parts, but the construction of theshift frame could be modified to adapt it to carriages of differentconstructions.

E represents a leg or part which is rigid with and depends from theshift frame substantially midway between the ends thereof. Forconvenience in manufacture this leg consists of a separate castingprovided with' a forked upper end forming two flanges e which arerigidly attached to the shift frame by four screws e frame,

F and G represent, respectively, the upper and lower members or links ofthe supporting link motion for the shift frame; The

uppper link or member F shown consists of' a bar extending transverselyof the machine beneath the shift frame and provided at its ends withcross arms f which extend forwardly and rearwardly and are suitablypivoted at their front ends to the shift frame at and are suitablypivoted at their rear en s to lugs or standards f2 rising from the rearportion ofthe top plate a of the main The lower vlink or member G issuitably pivoted at its rear end to a lug or standard g rising from thelower rear portion of the main frame and is pivoted at its front end tothe lower portion of the leg E. Preferably the lower forked and providedwith a fixed pivot'g, and the front end of the link Gr enters the forkedlower end of the leg E and 'has an upwardly opening slot in which thepivot g is removably seated. A spring g2, arranged between the link Gand the rear part of the main frame, holds vthe front end of the link upagainst the pivot g; The movement of the link G is limited by a stop orpin g which the link is adapted to strik'e. Preferably., the pivots,connecting the front ends of the upper and lower swinging' links ormembers F and G to the shift frame and leg E, are arranged in the samevertical plane, and the pivots connecting the` rear ends of theseswinging links or members to the main 'frame are also arranged in thesame vertical plane, and the .two links or members are of end of the legE is its two printing positions are directly overv i each other in thesaine vertical plane.

H H, Fig. 3, represent two coiled springs seated in cups la, in the topplate t beneath f the front end portions of the shift frame.

The upper ends of the springs bea-r in sock# ets in the shift frame,and, their lower ends are adjustably secured in holes in the bottoms ofthecupslt by set screws h. 'The set screws enable the springs to beadjusted so as to counterbalalnoe the weight of the shift frame andcarriagewith the nicety required to enable the carriage to be shiftedeasily and prevent its return by gravity sluggish.

The shift frame, mounted as described, is entirely supported by theswinging links or members and the springs H H, andin effect is adaptedto float or rise and fall vertically, but it does not have any slidingconnection with the main frame of the machine and is, therefore, freefrom sliding friction when shifting. The described Hoatingsupport forthe shift frame combines the advantages of the pivoted or oscillatingshift frame, heretofore, employed in the `Moyer machine, and of a'sliding shift frame, but it is free from the disadvantages incident toa sliding support. This construction has the advantage overconstructions in which theplaten is mounted to shift on the carriagethat no part of the shift mechanism partakes in the horizontal travel orletter space movements of the carriage, and the weight of thecarriage'is only about onehalf as great as those in which the shift iseeeted on the carriage by parts that travel Ahorizontally with thecarriage. The extra weight of such a carriage necessitates a carriagedriving spring tension several ounces greater than a carriage which ismounted on a shift frame such as described `which docs not travelhorizontally with the carriage. The actual difference in vpower requiredto set the carriage back for a. new line is of vital importance, andthereduced wear and noise on the escapement are alsoimportant?considerations. A sliding shift frame or support is prone tostick or bind in its guides and a 1 ery close and acpossible to avoidsliding friction, thus causof equal capacity v vcurate fitting isessential, v nich renders it im# ing the sliding` support to workhard.The

Heating support described has the further .advantage over the pri( roscillating or pivtion described, in Whleh' the front pivots 4move upabove the horizontal planes of the rear pivots to the same distance thatthey are normally below. these planes, the printing line on the platenis in exactly the same relation to the type bars in both positions ofthe platen, exceptV that one position is higher than the other, and eachof the two typeon each type bar faces directly to thei y rear when itstrikes the paper qu the platen.

vwithout altering the action thereof.

The upper link or member F, consisting of the bar with the end cross"arms f, is in effect the same as a pair oflrigidly connected links,

Aor a simple rock shaft having rigid arms at its ends, and'a frame ormember of either such form, or other form, could be used The member ismade in the form-shown to avoid interference wlth nearby parts ofthe machine.

The shifting mechanism for moving the 4 shift frame to shift the platenfrom one to another of itsprrnting positions is preferably substantiallythe 4same as that hereto- .fore employed in the Moyer machine, and.comprises a shifting cam I which is suitably pivoted at its lower endonthe lower rear Part of the type bar segment, andan antiriction roller1' which is suitably journaled on the leg or member E of the shift.frame and enters the cam slot of the cam I. The cam slot has aninclined middle portion for shiftin the shift frame and end portionssha-pe to prevent the shift frame and platen fromvibrating at the endofthe shift in. either direction.

K is a horizontal rock shaft which extends transversely of the machineunder the key levers and is provided at its central portion with a rigidarm [c connected to the cam H by aflink c extending between the twocentral type bar hangersor bearings on the segment. The rock shaft is-provioed at opposite ends with rockers or arms lc* `which bear and areadapted to rock on the rear ends of shift levers K which are pivotedbetween 'their ends and are provided at their front ends with operatingfinger keys. Wheneither of the shift keys is depressed the shaft K isrocked and acts through V'the arm=lc and link lc to move the cam Irearwardly and force the roller upwardly, thus moving the shift framesupport,ltogether with the shift frame and car- 'shift frame. K

N represents a rlbbon guide or vibrator .riage supported thereby fromtheno'rmal or lower position to the u peror shifted pos1-' tion. Aspring k3 coile about the rock shaft K acts to start the cam from 1tslocked shifted position as soon as the shift key 1s re- `.E thus locatedand the single lower link or y member G, hold the shift frame in properposition, just aswell as if a air of such links or members were employeat the opposite ends of thefshift frame and thegsingle cona leased, andlthen the weight of the shift nection is lighter, less expensiveandworks i with less friction. Another advantage ...0f

this construction is that it is quicker to assemble. The open seat orslot in the lower link or member G for the pivot on the leg or member Epermits the shift frame to be removed from the machine, leaving thelower link or member in place. y

L represents an abutment' adapted to be struck by margin stops-on thecarriage for limiting the horizontal travel Vof the carriagel two ofwhichv are employed, adjustably secured 'on the front 'or scale bar b ofthe carriage at opposite sides of the abutment. The abutment L islocated in a vertical o ening Z in the central front projection theshift frame and `is fixed to the inner end of a shaft Z2 whichis'suitably journaled on the front portion of thel shift frame. 'Aspring Z, Fig. 2,- coiled about tlieshaft Z2 acts to normallyhold .thefront end of the Z indicates one of the margin stops,

abutment up in line with the ymargin stops as seen in. Fig. 1, and alsoholds it in the right hand portion 'of the opening-Z. The abut-l mentshaft is provide/'d at its outer end with a rigid arm Z* which dependsfrom the shaft key'm. By pushing this key rearwardly the rear 'end ofthe rod M will engagethe arm Z and rock the shaft, thereby lowering thefront end of the abutment Lout of the path of movement of the marginstops. A

suitable spring m', Figs. 1 and 6, returns the push rod MA to its normalforward position. The abutment and its shaft shift with ythe shiftframewhen the latter is raised or lowered, but the -lovverfcnd of thear'm Z is opposite .the rear end of the push rod M in` both positions ofthe shift frame so that the lnward`lnovenlent of the pushkey ml willmove the abutment to clear the margin stops in just the same Way in bothpositions of the mounted to 'reciprocate vertically on the frontprojection d of the shift frame, and

'n is a vibrator lever for actuating the ribbon vibrator. The vibratorlever is fulcrumed beneath the abutment L in the forked upper end of thele E of the shift frame and as seen in Fig. 1 has a short horn n adaptedin one positlon of the abutment to be engaged by a depending lug n2 onthe abutment. `In the normal positlon of the abutment, shown in Figs. land 7, the horn n' on the vibrator level' is located at one side of thelug n2 on the abutment, and does not prevent the vibration of thevibrator lever. When, however, the margin stop at the right of theabutment L strikes the latter it moves the abutment to the left againstthe action of the spring Z3 thereby placing` as hereinafter described,this locks the carriage escapement, and forms what is commonly known asa line lock to prevent overprinting at the end of a line. If theabutment is lowered to clear the margin stop, as before explained, thespring Z3 will return the abutment to the right to its normal position,thereby releasing the escapement or line lock. But the .abutment will beheld down by the overlymg margin stop and a few more characters can beprinted, if desired. When the carriage is set back for a new line thespring Z3 will return the abutment to its normal elevated position assoon as it clears the margin stop, the abutment thus being ready toagain arrest the travel of the carriage. When it is desired to print atthe left of the established margin, the abutment is held down by thepush key m while the carriage is set over to the right as far as`desired, and as soon-as the carria e has -moved back to the left farenough or the abutment to clear the left hand margin stop, the abutment'will spring up into normal position ready to lock the line byintercepting the opposite margin stop.

The universal bar O or element for causing the operation of the ribbonvibrator and carriager escapement when the type bars are actuated andthe actuators P for the uni'- versal bar are arranged much the same asdisclosed in Patent No. 1,018,062, granted Feb. 20, 1912, to Oscar C.Kavle, assi or, but instead of the universal bar eingmounted on theunderside of the top late a, as shown in said patent, the universa baror rock shaft O- is journaled in depending bearing brackets o on theforked head of the leg E of the shift frame, so that the universal barmoves with the rshift frame. The actuators P consisting of curved barsarranged over the type bar bearings in position to be struck and movedby the type bars when the latter approach the platen, are carried byrods p suitably mounted on the under side-of thel top plate a to moveforwardly and rearwardly. The supporting rods p for the` arms p2 andoperate the universal bar in both positions of the shift frame. As thearms p2 are normally out of contact with the actuator rods p there is nofriction between these parts when the shift frame is shifted.

Q represents a rearwardly extendingarm or lever fixed to the universalbar for actuating the carriage escapement, to which this arm isconnected by means not shown, and R represents a lever which is actuatedby the larm Q and is connectedl by a vlink fr to the vibrator lever foroperating the latter. '1 The lever Ris pivoted at its rear end by a pinor' rivet 1" to the arm Q and has a hole r2 through which the universalbar passes and which is large enough to receive a sliding sleeve rs onthe universal bar. This sleeve is adapted to be slid lengthwise on theuniversal bar to a position in which it projects through the hole r2 inthe lever R and'its conical end enters a corresponding recess in the hubof the arm Q. The lever R also has a hole r* adapted to receive afulcrum pin s which is secured to ya rod S and extends parallel with theuniversal bar.l The rod S is arranged to slide endwise parallel with theuniversal bar in guide holes in the brackets fn, and is provided with aforked vcollar or part s which straddles a iange Tv the rod S can beslid to move the sleeve r into and the pin a out of en agement-v withthe levergR, or vice versa. he pin .s slides in a fixed lug or bearings* on the shift frame and this prevents the rod S from turning'andretains the pin s3 in the hole in the actuating rod .9"and compels therod S and sleeve 1" to move lengthwise only as actuated by the shaft T.f

a, Fig. 1, indicates a spring connecting the lever R to the shift framefor restoring the universal bar andthe connected levers to normalposition after actuation, In the position of the parts 'shownin Fig. 8-the sleeve r is seated in its holein the lever R and the vfulcrum p'in sis withdrawn from its ioo The collar s is.fixed on i push rod Mandactuatin ".tion. There issufliciefit top plate. a of the main framehas an hole in the lever. The lever R is then rigidly .connected to thearm Q to swing therewith as one the lower field or portion of the ribbonto and from printing position. When the slide rod is moved to theposition shown in Fig. 2 the lever R will swing) on the pin s as afulcrum, beine actuated y the pivot i" connecting it to t e arm Q.. Thehole r2 in the lever lt 'is large enough to allow the lever to swing onthe fulcrum s when the sleeve r is moved out of the hole. VThe throwofthe lever R will then be shortened to the requisite extent to vibratethe upper field or portion of the ribbon to 'and from printing position.This mechanism thus permits the use ofV a multi-color ribbon, or ribbonhaving two different kinds of fields or portions.

Since the universal bar, the carriage escapement, the ribbon vibratorand the connections between the same are all mounted on and shift withthe shift frame there is no relative movement and friction between theparts -when the platen is shifted. This construction also permits all ofthese-parts to remain in place on the shift frame and be removedtherewith from the machine. The 4 open central portion through whichthese parts pass when removingF the shift frame. The rod s remain. onthe top plate a when the s ift frame. and the carriage are detached, andwhen the shift frame is returned the pin enters the hole in the rod s3and-the arm assumes the proper relation to the push rod M withoutattenclearance between the pin and rod s and between the arm l* and pushrod M `'to prevent friction between the parts when theshift frame isshifted.

U represents a type bar' center guide which has legs rigidly secured inany suit'- able way to the top platefa of the, maini frame.

As shown in Figs. 2 .and 3, the top plate a of the main frame is formedwith a pair of rigid abutments V that rise therefrom at opposite sidesof and close to the front projection d of'the shift frame. Theprojection does not touch the abutments when the shift frame is shiftedup and down, butwhenever the carriage in moving in either direction isbrought to-a sudden stop solas to cause the link or member F tospring-or give, the projection d' is adapted to strike one or the otherof these abutinents and thereby prevent excessive strain on the link ormember F.

'.While the ribbon vibrating mechanism, the means for changing the throwof the vibrator, the margin stop device and thereleasing means thereforare believedto be of novel construction, they are not'claimed herein,except in combination wlth the aspart, and produces the` proper throw ofthe vibrator lever to movel sociated shifting means, the claims fortheseparts perse being reserved for a divisional f application.
